As the district court points out, this case is governed by the substantive law of Louisiana and its contours in this field are not well-defined. Standard Brands, Inc. v. Zumpe, 264 F. Supp. 254 (E.D.La.1967). Under the civil law of Louisiana, injunctive relief in such cases is equitable and discretionary. Louisiana Civil Code, Art. 21. See Standard Brands, Inc. v. Zumpe, supra, at n. 43, p. 271, and Young v. International Paper Co., 179 La. 803, 155 So. 231 (1934). The opinion in the case at bar was founded upon the correct concept of the rights of Wheelabrator Corporation and did not misconceive the import of the evidence.1 Based upon the fact determinations set forth in that opinion, we cannot find that the district court abused its discretion in refusing injunctive relief. Frosty Co. v. Dr. Pepper Co., 361 F.2d 124 (5th Cir. 1966) and Aerosonic Corp. v. Trodyne Corp., 402 F.2d 223 (5th Cir. 1968).
